Chocoholics breathed a collective sigh of relief a couple of years ago, when studies appeared touting chocolate as being good for you . But have we gotten used yet to seeing chocolate bars in the health-food aisles?

Dark chocolate (that's chocolate without milk as an additive, and that contains more than 15 percent cocoa solids, according to U.S. standards) contains antioxidant flavonoids, which are plant compounds that prevent free radical damage and can help respond to allergens, viruses, inflammations and carcinogens.

It's not actually green, but it might as well be. Gary Null's Nutritious Chocolate is packed with more vegetables than a health food salad bar. Sure, it also contains sugar and cocoa (both organic, of course), but they are quickly followed by a shocking list of ingredients that includes alfalfa leaf, oat grass, broccoli, parsley, and kale.
